4 lobe of the brain

Answer 24

frontal, parietal, occipital, temporal

Question 25

association area

Answer 25

an area that integrates input from different regions of the brain

Question 26

projection areas

Answer 26

perform more rudimentary or simple pereptual and motor tasks

Question 27

primary motor cortex

Answer 27

initiates voluntary motor movements by sending neural impulses down the spine

Question 28

Broca’s area

Answer 28

speech production- found in the dominant hemisphere- left hemi

Question 29

wernicke’s area

Answer 29

language reception and comprehension

Question 30

contralateral communication

Answer 30

hemispheres communicate with each other

Question 31

ipsilateral communication

Answer 31

only communication on the same side of the body

Question 32

dominant hemisphere

Answer 32

heavily stimulated during language reception and production. usually the left with broca and wernickes areas

Question 33

non dominant hemisphere

Answer 33

intuition, creativity, music cognition, and spatial processing

Question 34

acetylcholine

Answer 34

PNS- transmit nerve impulses to the muscles, CNS- attention and arousal , linked with alzheimeres disease because of the loss of cholinergic neurons

Question 35

epinephrine and norepinephrine and dopamine

Answer 35

catecholamines

Question 36

catecholamines are

Answer 36

known to control emotional experience

Question 37

epinephrine and norepinephrine

Answer 37

control alertness and wakefulness for the sympathetic nervous system to promote fight or flight response

Question 38

norepi

Answer 38

acts at the local level as a neurotransmitter
low levels = depression
high levels= mania

Question 39

epinephrine

Answer 39

secreted from adrenal medulla to act systematically as a hormone

Question 40

dopamine

Answer 40

movement and posture
imbalances play a role in schizophrenia - too much dopamine or over sensitivity to dopamine in the brain
Parkinson’s disease- loss of dopaminergic neruons in basal ganglia

Question 41

serotonin

Answer 41

play a role in regulating mood eating sleeping and dreaming

too much = manic state, too little= depression

Question 42

GABA

Answer 42

inhibitory postsynaptic potentials to stabilize neural activity via hyperpolarization

glycine

Answer 43

inhibitory via hyperpolarization

Question 44

glutamate

Answer 44

excitatory neurotransmitter

Question 45

neuromodulators

Answer 45

neuropeptides that are slow and have longer effects

ex: endorphins which are natural painkillers like morphine

Question 46

hypophyseal portal

Answer 46

paracrine communication between hypothalamus and pituitary gland

Question 47

adrenal medulla

Answer 47

releases epinephrine and norepinephrine

Question 48

adrenal cortex

Answer 48

corticosteroids- testosterone and estrogen

Question 49

rooting reflex

Answer 49

turning head in the direction of stimulus that touches the cheek

Question 50

moro reflex

Answer 50

infants react to abrupt movements by flinging out their arms and slowly retracting their arms while crying
